Major Changes Are Coming

Major changes are coming this week, with the Snowmiser making a return to Utah.

We'll have a fairly mild day tomorrow (Tuesday), but then a major upper-level trough and surface cold front approach Utah on Wednesday, which looks to be a day of transition.  

Following passage of the cold front, temperatures in the Wasatch will drop precipitously and we'll see a return to the Greatest Snow on Earth (in contrast to the Cascadian storm cycle we had last week).  In fact, by Thursday, 700-mb (i.e., crest-level) temperatures fall to around -18C over northern Utah. 

What this means in American units (degrees Fahrenheit) is sub-zero temperatures in the high alpine and high temperatures in the single digits near 8000 feet.  Time to break out the down or puffy jacket.
